Esther Short -- Clark County Public Works was heralded in an international infrastructure competition for its use of 3-D engineering software on the Salmon Creek Interchange Project. The county took second place in the Autodesk software company's Excellence in Infrastructure competition. Public Works was up against 42 other nominated projects from across the world. The Salmon Creek Interchange Project, budgeted at $133 million, will create a new interchange at Interstate 5 and Interstate 205. The project is in the final phase and expected to be completed in 2014. County engineers used 3-D technology to redesign roads near the interchange in the face of groundwater problems that caused the project's original design to be ditched, according to a county press release. Clark County won $5,000 in the competition. The interchange project was beat out by HYDROCHINA Kunming Engineering Corp.'s hydropower project in China.
